Sperm DNA fragmentation, recurrent implantation failure and recurrent miscarriage [PDF]

Asian Journal of Andrology, 2015
Evidence is increasing that the integrity of sperm DNA may also be related to implantation failure and recurrent miscarriage (RM). To investigate this, the sperm DNA fragmentation in partners of 35 women with recurrent implantation failure (RIF ...

Study Protocol: Effect of Lifestyle Modification on Sperm DNA Fragmentation Index

Journal of Pharmacy and Bioallied Sciences
Background: Infertility is a growing concern, affecting 8%–12% of reproductive-age couples worldwide. Male infertility accounts for 20%–30% of cases and contributes to 50% of fertility problems.

Effect of season on the dynamics of cat sperm DNA fragmentation [PDF]

BMC Veterinary Research, 2023
Background Feline species undergo reproductive seasonality; thus, sperm characteristics, such as DNA integrity, can be affected by the photoperiod. This study was conducted to determine the effect of seasonal changes on sperm quality and on the dynamics ...

Oxidative origin of sperm DNA fragmentation in the adult varicocele [PDF]

International Brazilian Journal of Urology, 2021
Purpose: Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown.

From pathophysiology to practice: addressing oxidative stress and sperm DNA fragmentation in Varicocele-affected subfertile men [PDF]

International Brazilian Journal of Urology
Varicocele can reduce male fertility potential through various oxidative stress mechanisms. Excessive production of reactive oxygen species may overwhelm the sperm's defenses against oxidative stress, damaging the sperm chromatin. Sperm DNA fragmentation,

Impaired semen quality, an increase of sperm morphological defects and DNA fragmentation associated with environmental pollution in urban population of young men from Western Siberia, Russia.

PLoS ONE, 2021
Poor sperm morphology and an elevated DNA fragmentation level are considered to be related to spermiogenesis malfunctions as a result of genetic mutations and effects of environmental factors, including industrial pollution.

Evaluation of Sperm DNA Fragmentation Using Two Different Methods: TUNEL via Fluorescence Microscopy, and Flow Cytometry

Medicina, 2023
Background and Objectives: Sperm DNA fragmentation refers to any break in one or both of the strands of DNA in the head of a sperm. The most widely used methodologies for assessing sperm DNA fragmentation are the sperm chromatin structure assay (SCSA ...
